I SAFETY. GATE.

Application filed octoberas', 1920. Serial no. 420,179.

To all whom it may concern:

Be it known that I, Gnoneii F. WINTER, a

citizen of the United States, residing at Los Angeles, in the county ofLos .Angeles and State of California, have invented new and usefulImprovements in Safety Gates of which t-he'following is a Specification.

This inventionis an improvement on the safety gate set forthinLettersPatent of the United States, No. 1,347,198, patented of the gate shownin Fig. 2, fully closed.

to me July '20, 1920, in which any edgewise moving closure for a passwayis arranged to accommodate a limb of aperson so as'to avoid injury tosuch linibif thesame is'in the way whenthe closure is shut. An object ofthis invention isto provide a novel form of safety gate involving'theinvention coveredby my saidpatent and to make provision wherebywhen thegateis closed, it forms as complete :a barrier at' the closure edge asat any :other part thereof; and to make'this true with respect to firescreen doors. 1

lVith this object in view I'pro'vide'the gate with a slide-way in" whichI yieldingl'y mount a rigid edge member that is relatively light so thatin case the gate is closed upon the body or upon it'lllllb, of a person,the edge member will allow the mainbody of the door to come toclosedposition while the edge member is'in open position, withoutcrushing or injuring the person, and to normally closethe passway whenthe path of'the gate is unobstructed;

This invention is applicable to grille work and wire glass elevatorgatesand to analogous edgewise closures.

In this invention a comparatively'narrow and light section is slidinglyor telescopically connected to a main body of the gate and is heldyieldingly extended by resilient means, as springs or the like, socas toclose the opening in conjunction with the main body ofthe gate. p

An object istoiorma complete passway closure without allowing themomentum of the main body thereof to' act to the injury of a limb orthebody of a person caught bythex gate inclosing.

Further objects, advantages and features of invention may appear fromthe accompanying drawings, the ,sirbjoined detail descriptionand theappended claims.

'The invention may be carried v out in various forms.

The accompanying drawings illustrate the invention in some of theforms'inwhicli it may be applied. v

In the form shown in Figs. 1-6, the: main body 1 is provided with aslide-way 4 at top and bottom in parallelism with each other andra sideface of the door; and the movable section 2 is'provided with aslide oineach slide-way. The spring means 3 operatesupon the slides .5 tonormally eX- tendthe. yielding 'section2 into position to complete theclosing of thepassway or door opening'o. Where double doors areemployed, one on each side of the passwayas shown in the drawings, oneside of the 'passioo llO

way is closed by a door 7, and the other half of the passway is closedby the door 1 and yieldingly mounted sliding edge section 2 tendedposition, also looks the main body 1; there being a seat 9 in the frameof the main body which is engaged by the bolt when said main body getsto its closed position and while the yielding extension 2 is retractedby the interposition of any obstacle as an arm or a limb indicated inFig. 4, is in the way; but as soon as the limb is withdrawn, theyielding section is extended by the resilient means 3 into passwayclosing position shown in Figs. 1, 2, 5, 7 and 8.

The extension 2 should be of as light construction as possible, dueconsideration being had to other conditions, so that when the elevatordoor is being closed by the usual pneumatic means, the momentum of theedge section 2 of the door will not be sufiicient to crush or injure thelimb or other portion of a human being caught in the opening or passway6.

The frame 10 of the yielding extension is rigidly connected to theslides 5 and fits snugly against the frame 11 of the main body 1; andthe latch 8 is controlled by pneumatic means 12 which may be of any wellknown construction and engages the seats 9 and 13 when passway 6 isentirely closed. The operator of the doors will manipulate a handle 13to control either the pneumatic device 14: or the electrical device 15as the case may be to withdraw the latch from looking position when. itis desired to open the door.

16 indicates the structure forming the. sides, bottom and top of thepassway, to which the closure is adapted.

Suitable means are provided to prevent the edge section 2 from beingdetached from the main section. 17 indicates detachable stops on slidemembers 5 working in slots 18 to limit the edgewise movement of thesections 2. I

I claim:

1. An edgewise moving closure for a passway, said closure comprising amain body to partially close the passway, and a section provided at oneedge of said main body and being movable relative thereto; and means toyieldingly hold said relatively movable section extended beyond the edgeof said main body to complete the closing of the passway; said meansbeing adapted to allow said movable section to be retracted in case thelimb of a person should interfere with of the main body of the closure.

2. An elevator door comprising an edgewise movable main body provided atone edge with a section movable edgewise relative to the main body;means to yieldingly hold said movable section extended from the mainbody to move said section into closed position to finally close the dooropening, and also adapted to allow the main body of the door to moveinto its closed position without closing the opening in case the limb ofa person should interfere with the movable section of the door at theclosing operation; and means to lock the movable section of the door inclosed position when the door is fully closed.

3. An edgewise moving closure comprising a main body having a slide-wayin parallelism with a face of the closure; an edge section having aslide movable in said slideway; means to prevent withdrawal of theslides from the slide-way; resilient means to extend the edge memberbeyond the edge of the main body and to yieldingly hold the edge sectionextended.

1. An edgewise moving closure comprising a main body having a slide-waytherein; an edge section having slides movable in said slide-way; meansto prevent withdrawal of the slides from the slide-Way; resilient meansto extend the edge section beyond the edge of the main body and toyieldingly hold the edge section extended; and means to lock said edgesection in extended position.

5. An edgewise moving closure comprising a main body having a slide-waytherein; an edge section having slides movable in said slide-way; meansto prevent withdrawal of the slides from the slide-way; resilient meansto extend the edge section beyond the edge of the main body; and toyieldingly hold the edge section extended; means to lock said edgesection in extended position; and means under the control of theoperator to release the lock from locked position.
